RESUMO
Technical assistance (TA) has been a ubiquitous part of the implementation of policies, programs, and services across public and private enterprise for decades. There have been few attempts to identify critical components of TA and evaluate its effectiveness. Qualitative analysis of interviews with experienced TA providers suggested a continuum of practice anchored at each end by approaches termed content-driven and relationship-based. Content-driven approaches focus on information transfer and referral whereas relationship-based approaches center on the facilitation of behavior and systems change. TA is almost always a mix of these approaches. Fitting the right approach to each situation is the key to success. The structure of TA is conceptualized as a three-phase set of activities (decision-making, implementation, and evaluation) supported by an effective partnership and informed by the overarching context. The strategies for effective TA are consistent with major theories of behavior change but need to be further evaluated and refined.
